GM Brazil Proving Ground Chosen For Federal Vehicle Efficiency Testing

General Motors has announced that the GM Brazil Proving Ground has been selected by Brazilian authorities to conduct federal efficiency testing.

The GM Brazil Proving Ground was selected by the Instituto Nacional de Metrologia, Qualidade e Tecnologia (INMETRO) to conduct the fuel efficiency tests that comprise the Brazilian Vehicle Labeling Program (PBVE), responsible for the Energy Efficiency Seal on all new vehicles sold in Brazil. The field will now host the federal fuel efficiency testing program.

“In the year in which we celebrate GM’s 100^th anniversary in Brazil, it is an honor for us to have our Proving Ground as the venue for INMETRO’s energy efficiency tests,” said Vice President of GM South America, Fabio Rua. “This is a fundamental initiative that benefits the entire national industry and guides companies in adopting more sustainable and transparent practices,” he added.

Specifically, the GM Brazil Proving Ground will carry out two phases of the PBVE efficiency program, offering all participating companies a structure to ensure standardization, agility, and accuracy in the results, which serve to guide consumers in the fuel consumption of the tested models. The first phase includes vehicle weighing, followed by the deceleration test, which evaluates aerodynamic efficiency and rolling resistance.

Each automaker will conduct testing at the GM Brazil Proving Ground with its own vehicles and staff, under the supervision of a team of INMETRO auditors at all stages. The first test at CPCA will feature 27 models, one from each manufacturer. The new 2025 Chevy Equinox EV, recently launched in the country, was the model selected by GM for the first federal efficiency measurement and regulation.

Officially known as CPCA for Campo de Provas da Cruz Alta (High Cross Proving Ground), the GM Brazil Proving Ground is more than 50 years old, and is now one of the leading automotive development centers in the Southern Hemisphere of the Americas. INMETRO selected the field based on technical criteria such as available infrastructure, operational capacity, and compliance with fuel efficiency testing requirements.
